Transcoder-aided region of interest streaming over heterogeneous networks for 360-degree video on demand

Virtual reality (VR) is becoming a hot topic and introduces new challenges related to the presentation of the content on mobile devices. For instance, how to display properly large size video frames such as those taken from 360-degree cameras, on a 7-inch mobile display and how to quickly respond to the user’s navigation within current views such as tilting, zooming, or even changing the angle of view of the scene. In this project, we want to conceive transcoder-aided adaptive region of interest streaming solution in which a transcoder (a media processor) extracts and transmits only part of the scene to the mobile, to reduce the bitrate consumption, with the flexibility of controlling the view upon user’s request. In addition, we will work on enhancing our current rate controller and congestion prediction method by adding information about the wireless network conditions to avoid video freeze and provide smooth video playback.
